Designed for those of us who love space, versatility and plush comfort, the Amplitude is ideal for outdoor adventures that return to the same camp site each evening, for car camping road trips, crag-hopping van life or hut-based expeditions. Its spacious contoured rectangular shape, with an ultra-wide circumference, is ideal if you love freedom of movement and hate that tight sleeping bag feeling. And no matter which way the weather turns, the Amplitude can be modified to suit. Zip yourself in and pull the internal drawcords tight to combat the cold. When the temperature heats up, the multiple-zips allow you to poke your toes out if you need a little fresh air or separate the top from the bottom of the bag and use it as a standalone quilt. Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. The generous allocation of high quality 750+ Loft down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. The panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm. Designed to integrate with all our sleeping mats and to create the ultimate in sleep system comfort, the Amplitude utilises simple removable adjustable webbing loops to connect your mat to your bag.
